" Like Eschenbach's stone, the Chintamani Stone is, apparently, also green in color, since Roerich is on record as also stating that the Chintamani Stone is similar in appearance to a species of meteorite known as Moldavite, which is dark green in color. If the Chintamani Stone is indeed Eschenbach's Stone of Heaven could it also be the original Philosophers Stone, which legends assert could turn a base metal into gold and a human into an immortal deity?
